Many vehicles owners may think in wrong way that because of the high temperature in summer, we need to lower the vehicles tyre pressure,such as the car tyre, agricultural tyre. While do you know the result of this action? It will increase the contact areas between the road surface and car tyre, then increase force of friction, accelerate car tyre wear. Tyre will increase temperature easily and gain the danger of tyre burst. So in summer we need to remain the normal tyre pressure.
